Can people please reply to this email rather than the other one so the ARM kernel list gets Cc'ed correctly.) Thanks. I have also changed the maintainer to me, which is just easier I think.

* [PATCH] ep93xx: Add support for Simplemachines Sim.One board @ 2010-01-20 20:06 Ryan Mallon 0 siblings, 0 replies; 3+ messages in thread From: Ryan Mallon @ 2010-01-20 20:06 UTC (permalink / raw) To: linux-arm-kernel The following patch adds support for the ep9307 based Sim.One board from Simplemachines. The code is based on the patches from Simplemachines for the 2.6.24.7 kernel available here: http://sim1.googlecode.com/files/linux-2.6.24.7-patches-20091001.tgz. Support for SPI and Audio is not included since we do not support them in mainline yet. The framebuffer support has been tested with a standard desktop monitor. LCD support is not included because I do not have hardware to test. I have specified the maintainer for this board as Nuccio Raciti (CC'ed), who is the maintainer for Simplemachine's 2.6.24.7 patches. If this is not okay, I can put myself as the maintainer.
